The height of described air inlet, air outlet forms radial flaring wind-force incidence angle and contraction-like flaring wind-force angle of emergence less than the height of heat exchanger.
Generally the coil pipe of heat exchanger constitutes height between 100 millimeters～200 millimeters, preferred 150 millimeters height.
The air inlet of described machine unit shell and the distance between the air outlet suitably increase on existing basis, make between the two distance greater than the height of machine unit shell, can prevent obvious sudden expansion and sudden contraction that air forms when flowing through heat exchanger place housing, and the bigger local resistance loss that occurs; Make that the air that flows through heat exchanger is more concentrated, face velocity is more even.
Coil pipe described in the utility model is laid the course by row, and promptly coil pipe has multichannel water inlet and water inlet; Multichannel water inlet and delivery port can independent separately entry and water outlets, but in order to control with easy to use, the multichannel water inlet adopts a total pipeline entry, and the multichannel delivery port converges into a total pipeline water outlet.
The change of the utility model coil pipe arrangement mode has caused the change of the water (flow) direction in the coil pipe, allows the sky G﹠W to replace the distributary mode of traditional fan coil against the cross-current mode, obtains better radiating effect with this; The mode that can implement is that the multichannel water inlet of coil pipe is positioned at air outlet one side simultaneously, and the multichannel delivery port of coil pipe is positioned at air inlet one side simultaneously, and every road water inlet is connected with corresponding delivery port, and current and wind direction form contrary cross-current.Contrary cross-current can be regarded complete adverse current as when air-water-to-water heat exchanger surpasses four rows, and under the constant situation of two kinds of fluid temperature (F.T.) conditions, contrary cross-current can obtain bigger heat transfer temperature difference than following current and cross-current.
The delivery port of described multichannel coil pipe is communicated with total delivery port on the machine unit shell, and the water inlet of multichannel coil pipe is communicated with total water inlet on the machine unit shell.
The utility model fan coil units has following advantage:
1, overcome the little deficiency of conventional rack face velocity, heat exchanger effectiveness is improved;
2, the outlet wind speed is big, and air supplying distance is far away;
3, blower fan inlet height, heat exchanger height, unit air outlet height dimension are close, and have avoided the generation and the inhomogeneous heat exchange of eddy current as far as possible;
